Metal determination in cosmetics by ICP

It is well known that heavy metals are found naturally in the environment in rocks, soil and water and therefore exist in the manufacture of pigments and other raw materials in all industries including the cosmetics industry. Some of these metals have been used as cosmetic ingredients in the past. In some cases, measures have been implemented to reduce the amount of heavy metals to which users are exposed, including prohibiting their use in cosmetics. Lead,arsenic, cadmium, mercury, antimony and chromium are the main heavy metal ingredients prohibited in cosmetics in most countries. Cosmetic manufactures have the responsibility to ensure their products do not contain any of these metals.
